Rook chess piece



FIG. 1 is a front elevational view of a rook chess piece showing my new design;

FIG. 2 is a top plan view thereof; and

FIG. 3 is a perspective view thereof.

The side views of the rook chess piece are identical to its front view shown in FIG. 1.

The characteristic feature of my design resides in the elliptical, disintegrating edges intersecting to form four interior curved surfaces which are visible through the apertures of the chess piece. A similar design is visible on the ceiling of the chess piece cavity when one looks upwardly through the apertures. 

The ornamental design for a rook chess piece, as shown and described.
